Agreed.

The question is if the students will be taught that the first non-native Americans came here because of within-Christianity fighting and persecution.

In fairness I haven't been in high school for a long time, I assumed they would have to. Otherwise how could explain the pilgrims, pointy hat enthusiasts?

Unclear if they are requiring excerpts from any other religions.

They should. I'm not particularly religious myself, but my gripe is when people try to dismiss the bible, quran, torah, buddhist writings, etc they are being willfully ignorant of major mobilizing forces throughout history..
